MATERIAL FOR COVERING PIPES, 84.0.

SEECIFICATION forming part of Letters Patent No. 491,836, dated February14,1893.

Application filed October 15, 1392. Serial No, 448,931. (No specimens.)

To all whom it may concern:

Be it known that I, J AMEs LUoAs CovEL, of Naples, in the county ofOntario and State of New York, have invented anew and ImprovedComposition of Matter, of which the following is a full, clear, andexact description.

The object of the invention is to provide a composition for treatingpaper and rendering it suitable for a pipe covering, refrigerator liningand roofing material.

Reference is to be had to the accompanying drawings, forining a part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 represents an edge view of a sheet of paper having the compoundapplied to it; and Fig. 2 is a longitudinal view ofapiece of piping witha succession of layers of the prepared paper, broken away, as appliedthereto.

The compound with which I prepare the paper consists of the followingingredients combined in or about the proportions stated, namelyz-Bestwheat flour two pounds, pul- V verized alum two ounces, arsenicone-fourth ounce, red lead one ounce,litharge one ounce, beef gallone-fourth ounce, the whole to be mixed with one gallon of water.

In the preparation of the compound, Ifirst dissolve the alu m,arsenic,and beef gall in the Water; then mix dry the flour, red lead andlitharge, adding a small quantity of the Water containing the alum,arsenic and beef gall, from time to time until a smooth paste-like massis obtained, after whichI add the balance of said water and stir untilthe whole is Well mixed. I then boil the lnixture with steam orotherwise, when it is ready for use. The compound is applied With a fiatbrush to the paper to be treated, and as many coatings of the same asrequired applied to the paper. When dry the new material or preparedpaper is at once formed; when applied to cold surfaces it takes longerto dry than when applied to hot surfaces. W'hen paper thus prepared withthe compound is applied to steam or hot water pipes, it efectuallyretains the heat and prevents radiation from the pipes andcondensationwithin. them, thereby making the pipes better capable of conducting thesteam or hot water long or short distances without loss of heat, and sosaving fuel. Also when applied to pipes for conveying cold Water, itbetter retains the temperature of the water and prevents the latter fromfreezinyg. Likewise with the proper paper and compound a series of airspaces can be formed around the pipe, one around the other and thusmaking the covering more efiectual.

Fig. 1 of the drawings shows the paper b with thecompound capplied toits surface; and Fig. 2 shows the prepared paperin aseries or Successionof any number of sheets or layers b' wound and secured around a pipe d,each one outside the other, thus making a series of coverings inpreference to asingle one, Whereby the pipe Will be better protectedaccording to conditions and exposure of the pipe.

Paper prepared or coated with my special compound will, when applied tometal surfaces, prevent them from rusting and add to the strength anddurability of the articles it is applied to, and thereby often preventaccidents. By reason of the special compound, a thinner covering of theprepared paper will suffice. vSuch prepared or coated paper too may beused to advantage as a lining for refrigerators and as a Substitute foriron, tin, slate or shingles in roofing and for other like purposes.

Having thus fully described my invention I claim as new, and desire tosecure by Letters Patent:- n v The herein described com position ofmatter for coating or preparing paper, consisting of wheat flour,pulverized alum, arsenic, redlead, litharge, beef gall and Water,combined essentially as herein set forth.
